An improved technique using the 3.579(54) MHz NTSC color burst frequency
distribution was described in this NBS circular a year or so later (1972,
believe):

I was a General class ham (then WA5ZBJ) just entering the UT Austin EE
school in 1972. I ha
The house standard in some stations are no more than LC oscillators.
As long as the relative timing between signals is constant, you can do
synchronous switching.
All signals go through as dedicated frame synchronizer that is
synchronized to house reference.
At the last station that I worked at,

Has anybody made a graph of the accuracy of house standards over time? I'm
looking for something like Moore's Law.

Does anybody remember that booklet? Did I get the story reasonably accurate?

Many years ago, I think it was late '70s, a friend showed me a blurb from
NBS. They were distributing time by piggybacking on NBC's signal. NBC had

power GPS signal would be a better future?
